Oil/water Temps

[Sebringjetta]

ok so i have searched and gone through the threads in regards to water and oil temps... it looks as if the temps are all over the place as the temps will change do to demographics, humidity, track temps etc.... so lets make it simple...

SO CAN SOMEONE TELL ME THE BELOW WHAT THE MAX YOU GUYS RECOMEND FOR THE FOLLOWING.... THANK YOU FOR YOUR TIME


ARVG/STREET DRIVING TEMP MAX TRACK TEMP


OIL TEMP

WATER TEMP

Temps are all over the place depending on how hard the driver pushes the car, humidity, etc...

The car will go into limp mode if it gets too hot. If you start getting warnings, you are on the edge, after that it will shut itself down. This happens somewhere around 300 oil and 235-240 water.

Thank you sir...

As stated, temps will vary significantly for a lot of reasons, but as long as the sensors are working properly, the car will protect itself from overheating. Fwiw though, when my engine is fully warmed up, on the street I'm always in the 195-225 F range for oil. On the track I don't think I've ever gone above 240 F or so, even though I'm in an advanced run group and have run on days when the ambient temperature was 107 F. I guess that's a testament to the M3's oil cooling! (Meanwhile the 335i's street running oil temp is 250 F. )

Where are you finding water temps? I read one of Mike Miller's Tech Talk replies in Roundel where he stated that BMW no longer shows water temperature because modern ECUs will adjust water temperature constantly for all kinds of reasons, and if the average owner saw those fluctuations on a guage, he/she would assume there was a problem when it was in fact perfectly normal. I have no way to confirm that, but Mike Miller is an extremely well-respected master BMW tech.

i have been running a scan gauge II for a few years now in my e46 m3 and have always watched the water temps as that was one of the weakest points for the e46 m3....im in the advance run group as well and in the summer time the temps would reach scary limits so it was always somthing i would watch while also running the heater to keep the temps under control

You can display water temps directly on the dash.

Exact instructions in the e90post track forum sticky on limp modes. (sorry, can't link, on mobile)
